I bought this two months ago, while a great cast iron oven, there are many imperfections resulting in rusting early VERY easily. You have to put this in the oven after each wash for 20 minutes, as per the instructions, this is a must. After two months, mine is rusting quite a bit right under the screw. The enamel coating on it is very thin, or at least a lot thinner than a Le Creuset.

that is really strange. they must have switched suppliers, as i have the previous kirkland oven, the round one, and have been using it regularly for over a year with none of the issues you have had. i don't do any post wash oven heating, only hand wash as instructed and air dry. . .it still looks brand new. don't put it in the dishwasher, and i don't think you'll have any problems. . .
